Fort Santa Agueda, on Guam Highway 7 in Hagåtña (formerly Agana), Guam, dates from about 1800, during the 1784-1802 administration of Spanish governor Manuel Moro. It was an uncovered fort with a manposteria (coral stone and lime mortar) parapet, rising about 10 feet (3.0 m) above a sloping hillside. It is listed on the U.S. National Register of Historic Places, as the only remaining fortification of the Spanish Era in Hagåtña.[1][2]
The fort was mentioned in 1802 by an officer of an American whaling ship, who recorded that the fort had seven guns and ten men, and that it fired a salute when the governor entered a new church in Agana. Russian Otto von Kotzebue, in 1817, noted that it had only a few guns. It was in ruins by 1887. It was used by Americans as a signal station until 1933, and was converted to a gun emplacement by the Japanese occupiers during World War II.[2]
